The IRS taxes savings account interest as ordinary income at your regular tax rate

Interest you earn on a savings account is taxed the same way as wages or salary — at whatever your ordinary income tax rate is. The bank reports this interest to the IRS on a Form 1099-INT, and you report it on your tax return. There is no special lower rate for savings interest, and you cannot avoid the tax by keeping the money in the account.

The amount of tax you owe depends on two things: how much interest you earned and what tax bracket you fall into. Someone in the 22% tax bracket pays more tax on the same interest than someone in the 12% bracket. The interest itself is small for most people — a savings account earning 4% or 5% annually on a $10,000 balance generates $400 to $500 in interest per year — but it still counts as taxable income.

Key Takeaways

  • Banks report savings interest to the IRS on Form 1099-INT, which you receive by January 31 each year.
  • You owe federal income tax on all savings interest at your ordinary tax rate, with no special deduction or exclusion.
  • Interest under $10 in a calendar year does not require a 1099-INT, but you still owe tax on it if you file a return.
  • State and local income tax also applies to savings interest in most states, adding to your total tax bill.
  • High-yield savings accounts earn more interest but also generate a larger tax bill in the same year.

When the bank sends you a 1099-INT and what it means

Your bank mails or emails you a Form 1099-INT by January 31 of the year after you earned the interest. This form shows the total interest you received in the previous calendar year. If you had multiple savings accounts, you may receive one 1099-INT per bank, or one combined form if the same bank holds all your accounts.

The bank also sends a copy to the IRS. This means the IRS already knows how much interest you earned before you file your return. You must report this interest on your federal tax return — either on Schedule 1 (Form 1040) if you file the long form, or directly on the 1040 if you use the short form. If you do not report it and the IRS notices the mismatch, you may face penalties and interest charges on the unpaid tax.

If your interest was less than $10 for the year, the bank may not send you a 1099-INT. However, you still owe tax on that interest if you file a return. You can find the exact amount in your account statements or by logging into your online banking portal.

Federal tax rates and how they apply to your interest

Interest income is taxed at your marginal tax rate — the highest tax bracket you fall into based on your total income for the year. In 2024, federal tax brackets range from 10% to 37%, depending on your filing status and total income. If you earn $50,000 in wages and $500 in savings interest, that $500 is taxed at whatever bracket your $50,500 total income puts you in.

This means the tax on your interest is not a flat percentage — it depends on your other income. A retiree with $30,000 in Social Security and $1,000 in savings interest pays tax at a lower rate than a working person with $80,000 in wages and the same $1,000 in interest. The IRS publishes updated tax brackets each year, and they change slightly to account for inflation.

You can estimate your tax bill by finding your tax bracket on the IRS website or using a tax calculator. Multiply your interest amount by your marginal rate to get a rough figure. If you expect to owe more than $1,000 in federal income tax for the year, you may need to make quarterly estimated tax payments to avoid penalties.

State and local taxes on savings interest

Most states tax savings interest as ordinary income, adding another layer of tax on top of federal tax. State tax rates vary widely — from 0% in states like Texas, Florida, and Wyoming to over 13% in states like California. If you live in a state with income tax, you owe tax to that state on your savings interest in addition to federal tax.

Some states offer small breaks for interest income. A few states exclude interest earned on savings accounts held for a certain period, or cap the amount of interest subject to tax. These breaks are rare and usually apply only to residents over a certain age or with lower incomes. Check your state's tax agency website to see if any special rules apply to you.

Local income taxes in cities like New York, Philadelphia, and Columbus also tax savings interest. If you live in one of these cities, you owe local tax in addition to state and federal tax. Your total tax bill on savings interest can easily reach 30% to 40% when you add federal, state, and local taxes together.

How high-yield savings accounts affect your tax bill

High-yield savings accounts earn 4% to 5% annually, compared to 0.01% at many traditional banks. This means a $50,000 balance in a high-yield account generates $2,000 to $2,500 in annual interest, versus only $5 at a traditional bank. The higher interest is taxable at the same rate as any other savings interest — you owe federal, state, and local income tax on the full amount.

The tax advantage of a high-yield account is not in the tax treatment itself, but in the fact that you earn enough interest to make the tax worth paying. If you earn $2,000 in interest and owe $600 in combined federal and state tax, you still come out $1,400 ahead compared to earning $5 in interest and owing $1.50 in tax. The higher interest rate more than compensates for the higher tax bill.

However, if you are in a high tax bracket or live in a high-tax state, the after-tax return on a high-yield account may be lower than you expect. Someone in the 37% federal bracket plus 13% state tax owes 50% of their interest in taxes. A 5% interest rate becomes a 2.5% after-tax return. This is still better than a traditional savings account, but it is worth calculating before you move your money.

What happens if you do not report savings interest on your tax return

If you receive a 1099-INT and do not report the interest on your tax return, the IRS will eventually notice. The IRS matches 1099 forms filed by banks against the tax returns filed by individuals. If there is a mismatch — the bank reported interest that you did not claim — the IRS sends you a notice and bills you for the unpaid tax plus interest and penalties.

The penalty for not reporting income is typically 20% of the unpaid tax, though it can be higher if the IRS determines the omission was intentional. Interest accrues on the unpaid tax from the original due date of your return, usually at a rate set quarterly by the IRS (currently around 8% annually). Over several years, these charges can double or triple the original tax bill.

If you made an honest mistake and report the interest as soon as you discover the error, you can file an amended return (Form 1040-X) and reduce the penalties. The IRS is more lenient with taxpayers who correct errors voluntarily than with those who are caught by an audit. Filing the amended return promptly shows good faith and can lower your total bill.

Strategies to reduce the tax on savings interest

You cannot avoid tax on savings interest, but you can reduce the amount of interest you owe tax on by using tax-advantaged accounts. Money in a traditional IRA or 401(k) earns interest tax-free until you withdraw it in retirement. Money in a Roth IRA or Roth 401(k) earns interest tax-free permanently, as long as you follow the withdrawal rules.

If you have a large amount of savings and expect to earn significant interest, consider splitting your money between a regular savings account and a tax-advantaged retirement account. The interest in the retirement account is not taxed in the current year, reducing your taxable income. This strategy works best if you do not need the money immediately and can leave it invested for several years.

Another approach is to hold savings in a 529 education savings plan if you have children or grandchildren. Interest earned in a 529 account is not taxed as long as you use the money for may have access to education expenses. If you withdraw money for non-education purposes, you owe tax on the interest plus a 10% penalty, so this strategy only works if you are confident the money will be used for school.

Frequently Asked Questions

Do I owe tax on savings interest if I do not receive a 1099-INT?

Yes. If your interest was less than $10 for the year, the bank may not send you a 1099-INT, but you still owe tax on it if you file a return. Check your account statements to find the exact amount and report it on your tax return. The IRS can still match your account to your return even without a 1099-INT.

What if I earned interest in multiple savings accounts at different banks?

Each bank reports interest separately on its own 1099-INT. You receive one form from each bank by January 31. Add up all the interest from all the forms and report the total on your tax return. If you have many accounts, your tax software can help you organize the numbers.

Can I deduct savings account interest as a business expense?

No. Savings account interest is personal income, not a business deduction. If you have a business savings account, the interest is still taxed as ordinary income. You cannot write it off against business expenses or reduce your taxable income with it.

Does the tax on savings interest count toward my standard deduction?

No. The standard deduction reduces your taxable income, but it does not change how savings interest is taxed. You report the interest as income, then subtract your standard deduction from your total income to find your taxable income. The interest is included in your total income before the deduction is applied.

What if I moved money between banks during the year and earned interest at multiple places?

Report all the interest you earned, regardless of which bank paid it or when you moved the money. The 1099-INT forms from each bank show only the interest earned at that bank during the time your money was there. Add them all together for your total taxable interest income.
